MATERIYIAL FORMING APPARATUS Filed oct. 9, 1928 Y Patented Nov. 24, 1931 f UNITED STATES PATENT OFFICE 'il' CHARLES EDWIN NELSON, 0F CHICAGO, ILLINOIS, ASSIGNOR TO WESTERN ELECTRIC COMPANY, INCORPORATED, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK MATERIALKFORMING APPARATUS This Yinvention relates to improvements in material forming apparatus, and more par? ticularly to improvements in apparatus for forming articles froml metal blanks.

"i n lThe principal object of the invention'is `theprovision of animproved apparatus of i simple and inexpensive construction for efficiently and expeditiously forming metal L lblanks into articles of'various predetermined llshapes.V i

' In accordancewith the general features of theinvention, there is provided in one embodiment thereof a material forming apparatus including a dial or disk Vhaving a face complemental to the periphery of a forming roll and provided with recesses for conveying metal blanks froma magazine into contact with the forming roll.,y Discharge or ejection of the formed article or part is effected automatically as the disk conveys them away from the forming roll.

Other Afeatures and advantages of the invention will become apparent from the following detailed description of one embodiment thereof, reference being had to the accompanying'drawings, wherein Fig. 1 is a plan view, partly broken away, of an apparatus embodying the featuresl of the invention;

Fig. 2 is a vertical section thereof` taken on line 2-2 of Fig. 1;

Fig. 3 is an enlarged view of the blank discharging means, taken on line 3 3 of Fig. 1, and

Fig. 4 is an enlarged fragmentary view of the portion of the disk in contact with the forming roll.

Referring now to the drawings in detail in which like numerals designate similar parts in the several views, there is disclosed a horizontally disposed base 10 having a vertically extending portion 11. In the horizontal portion 10 is` journalled a vertical shaft 12 on which is secured a horizontaliy disposed dial or disk 13, the top surface of which cooperates with a forming roll 14 mounted on a horizontal'shaft 15 journalled within the vertical portion or support 11. The top surface of the dial or disk 13 is complemental to the periphery of the forming l cesses.

roll 1 4 which has suitable depressions and elevationsto compress material into a predetermined shape. Recesses 18 provided at spaced pointsin vthe top surface of the dial 13 convey met-al blanks 19 from a chute or magazine 20 into contact with the periphery of the forming roll 14.

`As the dial or disk 13 conveys the formed metal blanks 19 away from the forming roll f a stationary ejecting member or obstruction 27 contacts the ends of the blanks 19 projecting from'the dial 13 and clauses the blanks to be thrown out of the recesses 18 into a suitable receptacle (not shown) located adjacent to the ejecting member.

The recesses 18 are most expeditiously con# structed by milling the top surface of the dial 13 into the shape which the formed blank of metal is to be depressed' by the roll 14, and then securing spaced platesv 23 thereto by means of screws 24. The spaces between the plates provide the necessary re- A vertical section of one form of Va recess so constructed is shown at 25 beneath the magazine 20, Fig. 2. In order that the plates 2 3 will successively 'pass under the forming roll 10, it is, of course, necessary that the top surfaces thereof comply with and be complemental to the'periphery of the forming roll 14; The thickness of the plates 23 must be greater than the extent of the greatest irregularity on the periphery of the forming roll 14 in order that the plates may be milled down to conform to the periphery of the roll, as shown in Figs. 2 and 4. As shown in Fig.4, the metal blank 19 being formed by the roll 14 preferably projects slightly above the top surface of the lplates 23 so `that it may be formed by theroll without the roll having to contact the plates.

The magazine 20 consists of an uprightl rectangular box orchute into the top of which the metal blanks 19 are passed inl stacked form, and from the bottom of which the blanks successively gravitate as the recesses 18 pass thereunder. The recesses 18 'are of just sufficient depth to receive a single blank, and while the plates 23 are passing beneath the magazine no blanks are conveyed therefrom, but the Vtop of the plate 23 con.-`

tacts with the undersurface of the next suc- Y ceeding blank, holding it against descent. The sides of the magazine extend down to a point Which almost contacts With the plates, thereby preventing the subsequent blank from being conveyed `by the dial or disk 13 until arecess approaches.
